Is it permitted to seat more than one passenger alongside of the driver?

1. It is absolutely forbidden.
2. Correct answer: No, unless it is stated in the vehicle registration.
3. Yes, if two seatbelts are installed, in addition to the driver’s seatbelt.
4. Yes, if the front seat is an integrated seat.

WhyOnly one passenger may sit next to the driver, unless the vehicle registration says otherwise. A bench seat or an extra belt does not change the rule.
